Question
Phospholipids commonly contain all of the following structural features EXCEPT:
A. a phosphate.
B. a phenol.
C. a glycerol backbone.
D. fatty acid chains.
Solution
The correct answer is B. a phenol. Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid "tails" and a hydrophilic "head" that consists of a phosphate group. The two components are joined together by a glycerol molecule. Therefore, phospholipids commonly contain a phosphate (A), a glycerol backbone (C), and fatty acid chains (D). However, they do not contain a phenol (B).
